Fly ash as an adsorbent for the removal of reactive blue 25 dye from aqueous solutions: optimization, kinetic and isotherm investigations; pp. 300–308Full article in PDF format
Fly ash obtained from a thermal power station was used as an adsorbent for the adsorption of reactive blue 25 dye from aqueous solutions. The parameters affecting the batch adsorption studies were optimized for this system. Lagergren’s kinetic models were used for the analysis of the kinetics of dye adsorption by fly ash. It was observed that dye adsorption followed pseudo-second-order kinetics. Batch adsorption experimentation data were fitted to two well-known isotherms: the Langmuir and Freundlich models. Regression analysis showed a good fit of the Freundlich isotherm model. Based on the adsorption studies it can be concluded that the fly ash can be used as effectual adsorbent for the removal of dye from aqueous solutions.
